JYM supplement Science are rocking the market with their Pre JYM workout Powder. Not only does it come in a variety of tasty flavours (and yes, it actually tastes good!) it also has the ingredients that your body needs pre-workout. Unlike most pre-workout powders Pre JYM actually lists the entire ingredients and the amount in each scoop. Since it is not hiding behind ‘proprietary blends’ like many products you know exactly how much of what you are ingesting – and the amounts look pretty good!
